Angle of Refraction Calculator

How to use the Angle of Refraction Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

n1×sin(a1)=n2×sin(a2)

a1_print = asin(n2/n1)

a2_print = asin(n1/n2)

Frequently asked questions

What is the angle of refraction?

The angle of refraction is the angle formed between the refracted light ray and the normal line at the interface between two different media. It is determined by the **index of refraction** of the two materials involved and is governed by Snell’s Law.

How does Snell’s Law relate to the angle of refraction?

Snell’s Law states that the ratio of the sines of the angles of incidence and refraction is constant and can be expressed as n1 * sin(θ1) = n2 * sin(θ2), where n1 and n2 are the indices of refraction of the two media, and θ1 and θ2 are the angles of incidence and refraction, respectively.

How can I use the angle of refraction calculator?

To use the angle of refraction calculator, simply input the index of refraction for both media and the angle of incidence. The calculator will automatically apply Snell’s Law and provide you with the angle of refraction.

What are the indices of refraction for common materials?

Here are a few common materials and their typical **indices of refraction**:

• Air: 1.0003
• Water: 1.333
• Glass: 1.5
• Diamond: 2.42

Can the angle of refraction be greater than 90 degrees?

No, the angle of refraction will never be greater than 90 degrees in normal circumstances. If the angle of incidence exceeds the critical angle, total internal reflection occurs instead of refraction.

Is the angle of refraction affected by wavelength?

Yes, the angle of refraction can be affected by the wavelength of light due to the phenomenon of **dispersion**. Different wavelengths of light have different indices of refraction in a given medium, which can lead to varying angles of refraction.
